IMPROVEMENT IN PAPER-MAKING MACHINERY.

Specification forming part of Letters Patent No. 59,661, dated November 13, 1866.

To all whom it may concern:

Be it known that we, STEPHEN G. ROGERS and GEORGE S. RoGERs, of Thetford, in the county of Orange and State of Vermont, have made a new and useful invention having referenoe to Machinery for Making Paper in a Continuous Sheet; and do hereby declare the same to be fully described in the following specification and represented in the accompanying drawing, which represents in vertical section our invention with those parts of a cylinder paper-machine with which it is directly connected-that is to say, the pressure-rollers.

In such drawing, A and B are the two -delivery or pressure rollers of a paper-machine. Between such rollers the endless blanket O and the sheet of paper S pass.

The paper, during its passage between the rollers, is very liable to adhere to and upon the upper one. The object of our invention is to prevent such adhesion of the paper to and winding of it on the said upper roller, and we successfully accomplish this by the employment of a third roller, D, which we arrange in front of the upper roller, and support the journals of such front roller in adjustable bearings provided with screws or other proper devices, by which the roller may be moved toward and pressed firmly up to the sheet of paper, which we cause to pass between such auxiliary roller and the upper of the pressure-rollers. The auxiliary roller also answers to separate the sheet of paper from the blanket or endless apron O.

The support for each journal of the auxiliary roller may be an inclined lever, E, provided with a screw, F, to pass through the said lever and screw into one of the standards G,for supporting the pressure-rollers. The said lever should turn on a fulcrum, a, for connecting it with the frame I of the machine.

hat we claim as our invention is The arrangement as well as the combination of the auxiliary roller D with the rollers A B and the delivery apron or blanket O of a paper-making machine, the purpose of such auxiliary roller being as set forth.
